Hi David,
Look at this:
%%%%%%%%%%%%%%%%%%%%%
\version "2.19.82"
\language "english"
#(set-global-staff-size 16)
strictGraceTrue = {
\newSpacingSection
\override Score.SpacingSpanner.strict-grace-spacing = ##t }
strictGraceFalse = {
\newSpacingSection
\override Score.SpacingSpanner.strict-grace-spacing = ##f }
\score {
\new StaffGroup <<
\new Staff { s4*5*2 }
\new Staff \relative { \time 5/4
r2
\strictGraceTrue
\tuplet 3/2 4 {r8 \acciaccatura a'' g-. \acciaccatura a g-.
\once \hide TupletBracket
\acciaccatura a g[-. r \acciaccatura a g]-.
\acciaccatura a g-. \acciaccatura a g-. r} |
\noBreak \strictGraceFalse
\tuplet 3/2 4 {\once \hide TupletBracket \acciaccatura a g8-.
\acciaccatura a g-. \acciaccatura a g-.
r \acciaccatura a g-. \acciaccatura a g-.}
\acciaccatura a g-.
r r2 |
}
\new Staff \relative {
r2 g''16-. g-. e'( c) g-. g-. e'( c) g-. g-. e'( c) |
\grace s8 g=''16-. \strictGraceTrue g-. e'( c) r4 g16-. g-. e'( c)
r8 e,16-. fs-. g-. a-. b-. c-. |
}
>>
}
%%%%%%%%%%%%%%%%%%%%%%%%%
I'm sorry I don't have time to write a full explanation, or more tests now,
but I think the problem lies with the fact that the bar starts with an
acciacatura in one Voice, but there is a bar check and no acciacatura in
the other Voice. Writing an acciacatura with a spacer rest in the voice
that has no printed grace note solves the issue. To avoid having the grace
(that occupies no time with the strict-grace-spacing set to #t) collide
with the barline, I changed spacing sections.
Hope this helps,
Stéfano
